Petrogenic organic carbon weathering and its controlling factors—a review
Petrogenic-derived organic carbon is an important carbon storage on Earth. Oxidation of petrogenic organic carbon releases carbon dioxide into the atmosphere—a key process in the geological carbon cycle. This process is of great significance for maintaining long-scale carbon balance on Earth and long-term habitability of the Earth’s surface environment. In recent years, research advancement has been made on petrogenic organic carbon weathering. This paper systematically reviews the current research status at home and abroad, focusing on carbon structural properties, quantitative methods for weathering rate, weathering controlling factors, and weathering flux statistics, in order to improve systematic understanding of petrogenic organic carbon and promote in-depth research on related key scientific issues.
